Aren't outlets downstream of a GFCI protected by the GFCI? That's why you can have a kitchen full of outlets with only one GFCI but all of the outlets are protected. If you've got a circuit with (from the breaker) 2 outlets, then a GFCI and then 2 more outlets, then the GFCI and last 2 would be protected, but the first two (closest to the breaker) would not be protected. And those two would be considered downstream while the 2 unprotected ones would be considered upstream.
